I'm wondering about converting my new-to-me K-Line scale Hudson to have 4 chuffs per rev. Does this locomotive have physical cams on an axle, reed switches, flywheel tape, or chuffing handled completely by the electronics? I was only worried about the sound, I will probably leave the smoke alone until I get brave enough for a motor swap. Also, why does it have two 9V battery terminals inside of the tender? I replaced the battery that was in there since I run on conventional, but didn't plug anything into the other one.
This engine is a real beauty, too bad I don't have a proper passenger train for it...
It is not well documented but K-lines cruise electronics also had the ability to generate 4 chuffs. It probably was not used because of the puffer smoke unit that is driven by a 2 lobe cam so they just used a micro switch. I converted my Hudson to 4 chuffs with a simple wiring and program change . I wish I could remember how I did it as I have lost the instructions I used. Of course the smoke only puffs every other chuff. I need to put a fan driven unit in to fix that.
